For use on that noisy chrome vibrator I suggest you use a shoulder rig so it doesn't shake out and fall on the road.
Also, consider some mufflers, you're making the more sensible of us look bad. Consider the arguments we provide for suppressors:
"I don't want to worry about hearing damage."
"I don't want to bother my neighbors."
I'm pretty sure that with those drag pipes, you're doing both.
